Overview

The Template acts as a layout for pages. It contains an html layout for the page and contains method calls which are answered by helper methods or the loaded yaml of a page.

Templates now support ERB or Haml for rendering.

  • template.html.haml

  • template.html.erb

  • template.html -> defaults to ERB
